Another game (new time limit)

I have entered a tournament in January with a G/45 time limit. In order for my wife and me (she might play too) to get some training in before the tournament, we decided to change the time limit of the games we've been playing from G/10 (3 sec delay) to G/45 (5 sec delay). Perhaps this will result in increased quality in our games, although I wouldn't necessarily bet on this. Hopefully, it will at least reduce the number of blunders.

RMD - ALD, 12/28/2004 [B31]

1. e4 c5 2. Nf3 Nc6 3. Nc3 d6 4. Bb5 Bd7 5. O-O Nf6 6. d3 [This was played in Matulovic-Velimirovic, 1973; more common are 6. d4 and 6. Re1.] g6 7. Bf4 Bg7 8. Bxc6 Bxc6 [=] 9. h3 [I don't really see the point of this move.] Qd7 10. Bg3 [10. Re1] O-O 11. Qe2 b5! 12. d4!? [12. Qe3] b4 13. e5 [13. d5] dxe5 [13. ... Nh5] 14. dxe5 [14. Nxe5] Nh5 15.

R6d3 Rxd3 23. cxd3 [This leaves the pawn backward as a target on the semi-open file. Better is 23. Qxd3.] Rd8 24. Rf1 [24. Rd2] Be7 [24. ... Rd5] 25. g4 a5 26. h4 [26. Nd2] Bf8 [26. ...

I gave serious consideration to 33. ... a4!? 34. bxa4 Qxa2 but ruled it out as too risky. But as it turns out after 35. Qxc5 Qxa4 36. Kg3 b3 the advantage lies with Black.] 34. Kh3 h6 35. g5 [Over the board I considered this move inferior, but post-mortem analysis reveals it to be correct.] h5 36. g4 hxg4+ 37. Kxg4 Qc6 [The elapsed times at this point were White 0:30 Black 0:35.] 38. h5 gxh5+ 39. Kxh5 Qc7 40. Qe4 Kg8 41. g6 fxg6+ 42. Qxg6 Qf7 [Best was 42. ... Qc6 43. Kg4 Kf8 =; now White has an edge.] 43.

Nxc5 Bd2 is likewise insufficient to hold the draw.] 50. Kd5? [This allows the Black King in. 50. Kd6 Kf7 51. Ne5+ Ke8 52. Nc4 Bd8 53. Kxc5 gave White the best winning chance.] Kd7 51. Ne5+ Kc7 52. Kc4 [52. Nc4!] Kd6 53. Nf7+ [The last chance was 53. Kb5 but after 53. ... Bc7 54. Nc4+ Kd5 55. Nxa5 Bh2 56. Nc4 Bg1 57. Nb6+ Kd4 58. Nd7 Kd5, White has won a pawn but the position is drawn with best play.] Kc6 [I offered a draw here, but my wife wanted to play on. The rest of the game doesn't really warrant any comment.] 54. Ne5+ Kd6 55. Nf3 Kc6 56. Ng5 Bd8 57. Nf7 Be7 58. d4 cxd4 59. Kxd4 Bc5+ 60. Kc4 Be7 61. Ne5+ Kb6 62. Nd7+ Kc6 63. Nb8+ Kb6 64. Nd7+ Kc6 65. Ne5+ Kb6 66.

Keene's Latest "Book"

World Chess Championship - Kramnik Vs Leko 2004
Ray Keene
£10.99/$17.99
157 pages, Hardinge Simpole

Less than 10 days after the match ended the book of the tournament has already hit the shelves


I have been racking my brain but have been completely unable to figure out any scenario in which this is a good thing. A world championship match, and the book is out in 10 days? Superficial-analysis much? If I wanted silly superficial inaccurate off-the-cuff analysis with no depth, I'd analyze the games myself. Keene has been an obscene hack for a long time, but this just takes the cake. What a joke!

Two Games

RMD - ALD, 12/26/2004 [C50]

1. Nf3 Nc6 2. e4 e5 3. Bc4 Bc5 4. O-O Nf6 5. Nc3 O-O 6. Bd5 [6. d3] Re8 7. d3 d6 [7. ... Nd4] 8. Ng5 [8. Bg5] Nxd5 9. Nxd5 [=] Ne7? [A mistake; 9. ... h6 is correct. - RMD] 10. Qh5! [I had only seen 10. Qf3. Had I seen this I would not have played 9. ... Ne7.] f6??? [10. ... Nxd5 does not work, but 10. ... Ng6 hangs on although White is obviously much better.] 11. Qxh7+? [Misses a mate in three with 11. Nxe7+! Rxe7 12. Qxh7+ Kf8 13. Qh8#.] Kf8 12. Qh8+? [Missing the much stronger 12. Nxf6! when Black's best is 12. ... d5 (to free up the square d6 for the King's escape) 13. Qh8+ Ng8 14. Qxg8+ Ke7 15. Qxg7+ Kd6 16. exd5 with a strong attack.] Ng8 13. Nf3 [13. b4!? was worth considering.] c6 14. Nc3 [White has won a pawn, but the attack has dissipated.] Bg4 15. Nh4 Kf7 16. Qh7 [16. Nf5] Ne7 17. Nf5? [Now this is a mistake; 17. Bh6!] Bxf5 18. exf5? Rh8! White resigns

As my wife and I occasionally do, we agreed to re-play this game from White's 15th move since my wife was not happy with 15. Nh4, although I did not see anything wrong with it.

RMD - ALD, 12/26/2004 [C50]

1. Nf3 Nc6 2. e4 e5 3. Bc4 Bc5 4. O-O Nf6 5. Nc3 O-O 6. Bd5 Re8 7. d3 d6 8. Ng5 Nxd5 9. Nxd5 Ne7 10. Qh5 f6 11. Qxh7+ Kf8 12. Qh8+ Ng8 13. Nf3 c6 14. Nc3 Bg4 15. h3 [I think the original 15. Nh4 was better.] Bxf3 16. gxf3 Kf7 [16. ... d5] 17. Qh4 [17. Qh5+ Kf8 18. f4] Ne7 18. Qg3 Rh8 19. Na4 [I thought my wife was shifting her attention to the queenside, but she did not follow up this move. She didn't even trade the knight for my bishop. I think continuing on the kingside with 19. f4 was better.] Qd7 20. Kg2 Rh7 21. Be3 Bxe3 22. fxe3 Rah8 [22. ... Rh6] 23. Rh1 Ng6 24. Rh2? [24. Rag1] Nh4+ [Missing 24. ... Rh5! (threatening ...Rg5) 25. h4 Nxh4+ winning back the pawn with the better position.] 25. Kf2 f5 [25. ... Rh6 - RMD] 26. Rah1 [26. Nc3] Kf6 27. f4 [27. Rg1] exf4 28. exf4 Re8 29. Qg5+ Kf7 30. Nc3 g6 [30. ... Qc7] 31. a4 [Another move which does not follow from or lead to anything else in the game.] Rh5 32. Qg3 Re6 [Wasted move; 32. ... Qd8.] 33. Re1 Re8 [33. ... fxe4 34. dxe4 d5] 34.

Rf1 to take advantage of the fact that I did not push the f pawn.] Re3 52. Rf1 Kxh3 [This was the pivotal decision of the game; I believe 52. ... Kg5 was stronger. - RMD] 53. Rxf5 Re7 54. b4 [54. a5!?] Kg4 55. Rf8 Kg5 [55. ... Rc7] 56. a5 bxa5 57. bxa5 Rc7 58. a6 Rh7 59. Rc8 Kf5 60. Rxc6 Ke4 61. d5 Rd7 [Chessmaster suggests 61. ... Kf5, but after 62. Re6 Black's chances in the endgame aren't any better than in the actual game.] 62. d6 Ke5 63. Kc5 Ke6 [63. ... Rd8] 64. c4 Ke6 [64. ... Rg7] 65. Kb4? [65. Kc7 Rxd6 66. Re7+ Re6 67. Rxe6+ Kxe6 68. Kc6 and White wins.] Kd4? [I was scared to trade rooks, but the only drawing chance lay in 65. ... Rxd6 66. Rxd6 Kxd6. Now White's win is just a matter of (very simple) technique.] 66. c5 Kd5 67. Rc7 Rd8 68. Rxa7 Kc6 [68. ... Rf8] 69. Rb7 [69. Kc4] Rf8 70. Rc7+ Kd5 71. a7 Ra8 72. Kb5 [72. d7] Ke6 73. Kc6 Rd8 74. Kb7 0-1

Tratado General de Ajedrez

For those who can read Spanish, I highly recommend the four-volume Tratado General de Ajedrez by the late Argentine master Roberto Grau. Although Grau died in 1944, this book has been reprinted many times since then, and I recently came across a $10 copy of volume 1 on the internet here. I think these four volumes (over 1500 pages all told) have everything you need to go from rank amateur to expert.

Volume 1 ("Basic Principles") starts off at the very beginning with the movement of the pieces, simple mates, and elementary tactical concepts like the pin. It also has a great number of short games to work through and many exercises. Volume 2 ("Strategy") goes through a detailed discussion of strategy - the fight for the center, etc., and attack and defense concepts (e.g., the sacrifice on h7, etc.). There are also a good number of classic grandmaster games, analyzed in a great deal more detail than the games in volume 1, with detailed text explaining the ideas behind a position as well as lengthy analytical variations. Once you have mastered the material in the first two volumes, I would be amazed if you did not have a rating in the neighborhood of 1600.

Volume 3 ("Pawn Formations") and Volume 4 ("Advanced Strategy") -- which I have not finished working through -- look to have everything you would need to get from 1600 to expert territory (2000). I would rank them on a par with Dvoretsky's series in terms of pedagogical quality (but with lower expectations regarding the reader's expertise, as well as with more analytical mistakes).

Four Games

ALD - RMD, 12/5/2004 [C42]

1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4 4. Qe2 d5 [4. ... Qe7 or 4. ... d6] 5. d3 Qf6? [5. ... Qe7] 6. Nxf7? [Way to throw an opportunity away. After the natural 6. Nf3, I would have won the Knight. Now the position is even.] Qxf7? [With 6. ... Qxf2+!, Black would even have recovered the pawn.] 7. dxe4 d4 8. Qb5+ Nc6 9. Bc4 Qd7 [9. ... Qg6] 10. Bg5 [10. O-O] Qg4 [10. ... Bd6] 11. Qd5 Qd7 [Qf7+ isn't really a worrisome threat; 11. ... Ne7.] 12. Qxd7+ Bxd7 13. O-O Be7 [13. ... h6] 14. Bf4 [14. Bxe7 Kxe7 15. f4] O-O-O 15. c3 [15. Nd2] Bc5 [15. ... Bf6 16. cxd4 Bxd4 is more accurate.] 16. Rd1 [Because of Black's slight inaccuracy on the last move, White now has 16. b4 Bb6 17. b5 Na5 18. Be2. Otherwise, 16. cxd4 Bxd4 is also an OK way to proceed. The move I selected is a non sequitor.] Bg4 17. Rd2 Rhf8 [Black's pressure provides sufficient compensation for the pawn deficit, so the position is basically even.] 18. Bg3 a6 [18. ... Rfe8] 19. Rd3 [I was trying to set up f3, but this move doesn't actually help make that possible; 19. Bd5.] Be2 20. Be6+ Kb8 21. Rd2 Bb5? [21. ... d3!] 22. c4 Rfe8 [22. ... Ba4 23. b3 d3 gave Black more counterplay than this.] 23. Bd5? [Duh! Of course 23. cxb5 since if 23. ... Rxe6, 24. bxc6. Now Black has a chance to escape.] Bxc4? [23. ... Nb4! 24. Na3 (24. cxb5? Nxd5!) Ba4 25. b3 Bd7 =] 24. Bxc4 Rxe4 25. Re2 [25. Rd1] Rxe2 26. Bxe2 d3 27. Bd1 Nb4 [27. ... d2] 28. Nc3 Bd4 29. Rc1 [29. Bb3!] Bxc3 [29. ... d2! 30. Ra1 Bxc3! (removing a defender of d1) 31. bxc3 Re8! (threatening mate) with strong winning chances.] 30. Rxc3 Nxa2? [30. ... Rd7] 31. Bxc7+ Kc8 [31. ... Ka7 is better, but Black is lost in any event.] 32. Bxd8+? [32. Bg4+! Rd7 33. Rxd3! with an immediate win.] Nxc3 33. bxc3 Kxd8 34. Kf1 b5 35. Ke1 Kc7 36. Kd2 a5 37. c4 [37. Kxd3] Kb6 [37. ... bxc4] 38. cxb5 Kxb5 39. Kxd3 Kb4 40. Ke4 a4 41. Bxa4 Kxa4 42. f4 [It's all over now. Even I couldn't screw this position up.] Kb4 43. g4 Kc5 44. Ke5 g6 45. h4 Kc6 46. Ke6 Kc7 47. f5 gxf5 48. gxf5 Kd8 49. Kf7 h5 50. Kg7 1-0

ALD - RMD, 12/23/2004 [D07]

1. d4 d5 2. c4 Nc6 [My wife loves this defense, yet I've never learned to play against it properly.] 3. Qa4 [While this move does make an occasional appearance in master play (3. Nf3 Bg4 4. Qa4 = appears as D07/1), I don't really like it. I regretted playing it the second I hit my clock. 3. Nf3, 3. Nc3, 3. cxd5 and 3. e3 are all more common, as well as more suited to my style.] Bd7? [This loses a pawn, although I overlooked it. Correct is 3. ... e6.] 4. Qb3? [I didn't play 4. cxd5 because I mistakenly thought Black could respond 4. ... Nxd4.] Nxd4 [4. ... dxc4] 5. Qd3 [On this square, the White Queen interferes with White's development. Better to abandon the bad strategy commenced on the third move by playing 5. Qd1.] e5 6. cxd5 Nf6 7. e4?! [7. Nc3] Bb4+ [Missing 7. ... Nxd5!? 8. exd5 Bf5 9. Qd2 Bb4 10. Nc3 Nc2+ 11. Kd1 Nxa1.] 8. Bd2 a5 [Chessmaster says 8. ... Nxd5!? is still playable, but I don't see it myself.] 9. a3 [It was time to continue developing with 9. Nc3; I don't know what kind of hypnosis I was under in this game.] Bc5 [Missing 9. ... Ba4! when White can't play 10. axb4 because of 10. ... Nc2+.] 10. Nc3 Nb3 11. Rd1 Ng4! 12. Be3 [12. Nh3] Bxe3 13. fxe3 a4 14. h3??? Nf6? [Missing the mate in three with 14. ... Qh4+!] 15. Nf3 [After all the back-and-forth swings, this position is esentially even.] Nc5 16. Qc2 Qe7 17. Bd3 O-O 18. Nb1 [I was planning Nb1-d2-c4 to put pressure on the e5 pawn, but this plan is absurdly slow. Much better was 18. O-O.] c6 19. dxc6 Bxc6 20. Nbd2 Rfd8 21. Nc4 [21. Be2 is better, although White is already worse off.] Nfxe4 [Or 21. ... Rxd3 22. Rxd3 Bxe4 23. Nfxe5 Nxd3+ 24. Nxd3 Rd8 with the edge for Black.] 22. Nfxe5? [22. O-O was way overdue! Now it's all over for White!] Qh4+! 23. Kf1 Ng3+ 24. Kg1 Nxd3 25. Rxd3 Be4 26. Rxd8+ Rxd8 27. Qf2?? [27. Nf3] Rd1+! 28. Kh2 Rxh1#

As a side note, this game reinforced the fact that my wife's opening repertoire is about 100 years out of style (although perfectly solid and playable nonetheless). Against 1. d4, she plays either the Queen's Gambit Accepted or the QGD Chigorin Defense as in this game. She never even thinks about any of the Indian Defenses. Against 1. e4, she responds 1. ... e5 - never the French or the Sicilian. With White it's 1. e4 almost 100% of the time, and if I respond 1. ... e5, she plays Giuoco Piano or the Ruy Lopez Exchange Variation. I am always torn between spending some time studying these openings or spending time studying variations I am more likely to see from other players in a tournament.

ALD - RMD, 12/26/2004 [D07]

1. d4 d5 2. c4 Nf6 3. Nc3 Nc6 4. cxd5 Nxd5 5. e4 Nxc3 [At the time, I saw this move as unnecessarily giving up the center, but after the game a quick review of ECO demonstrated that this is quite playable.] 6. bxc3 g6 [6. ... e5 immediately.] 7. Bc4 [7. Nf3] e5 [As long as 6. ... g6 was played, this should be followed up with 7. ... Bg7.] 8. d5 Ne7 [The counter-intuitive 8. ... Nb8 is also worth considering, as happened in Ratner-Terpugov, USSR 1950 (without the intervening Bc4 g6).] 9. Bb3 [9. Nf3] b5 [Huh?] 10. Ne2 Bg4 11. f3 Bd7 12. O-O f5!? 13. a3 [13. a4!] Bg7 14. Bb2 Qb8 15. Qd2 Qb6+ 16. Kh1 f4 [Prematurely releases the pressure on White's center.] 17. c4 O-O-O? [The straightforward 17. ... bxc4 18. Bxc4 Rb8 is necessary.] 18. Nxf4 exf4 [18. ... Rhe8] 19. Bxg7 bxc4? [Trying to be too slick. The plain 19. ... Rhg8 is correct.] 20. Bxh8 [White had better with 20. Bxc4 Rhg8 21. Bd4 c5 22. Bxc5 Qxc5 23. Ba6+ Kb8 24. Rab1+ and a clear win.] cxb3 21. Bd4 c5? [In this line this is not playable; 21. ... Qb7.] 22. dxc6e.p.? [22. Bxc5! when Black has lost a pawn for nothing since 22. ... Qxc5? is not possible because of 23. Rac1!] Bxc6 [22. ... Be8] 23. Bxb6 [23. Rfd1] Rxd2 24. Ba5? [I didn't think so at the time, but there is time for White to play 24. Bxa7!] Re2 25. Rab1 Re3 [25. ... Ba4 is a better way to defend the pawn.] 26. Rfc1 Kb7 27. Rc3 [27. Bd8 Nc8 28. Rc4] Ba4 28. Rc7+ Ka6 29. Bd2 Black resigns

Neither my wife nor I are prone to premature resignation, but in this game I thought my wife could have fought on for at least a while longer. After 29. ... Nc8 30. Bxe3 fxe3, Black is down both exchanges but has two passed pawns as compensation. Of course, with best play I should win, but she should know better than to expect best play from me.

RMD - ALD, 12/26/2004 [C68]

1. Nf3 Nc6 2. e4 e5 3. Bb5 a6 4. Bxc6 dxc6 5. Nxe5 Qd4 6. Nxf7? [My wife and I had reached this position once before on 11/27, and she played this move then too. I still don't understand the need for this desperation.] Qxe4+ 7. Qe2 Qxe2+ 8. Kxe2 Kxf7 9. d4 Nf6 10. f3 [The first deviation from our previous game, where my wife played 10. Bf4, which is better than the move in this game.] Bf5 11. c3 Bxb1 [11. ... Re8+] 12. Rxb1 Bd6 13. Kd3 Rhe8 14. b4 [14. Bg5] Nd5 [14. ... b5!? is a move I didn't even consider, but it's definitely worth looking at.] 15. a3 [15. a4] Nf4+ [15. ... Bf4] 16. Bxf4 Bxf4 17. g3 Bg5 [17. ... Re3+ was worth considering, but if not that then I should have played 17. ... Bd6. What I chose just allows White to play 18. f4 with gain of tempo.] 18. f4 Bf6 19. Rhf1 [19. g4] Rad8 20. g4 Kg8 [I considered this move as well as 20. ... Kg6. However, it turns out that 20. ... Be7 was best.] 21. g5 Be7 22. c4 [22. h4! At this point, I was thinking that White has the initiative but Black is definitely winning. I knew that as long as I didn't blunder it was in the bag.] b6 [The first inaccuracy. Better was 22. ... c5 23. d5 c6 stemming Black's initiative.] 23. Kc3 [23. Rbe1] c5 [A second inaccuracy. Now 24. dxc5 bxc5 25. b5 axb5 26. Rxb5 would give White an outside passed pawn.] 24. d5 [Not bad, but not fully capitalizing on Black's error.] cxb4+ [A third inaccuracy; 24. ... Bd6] 25. axb4 c6? [And now finally a downright error. I analyzed all sorts of replies to this but somehow missed the obvious 26. dxc6. I can't believe I was playing so badly that I made four consecutive bad moves. My wife's initiative was making me lose my cool.] 26. dxc6 Rc8 27. b5 axb5 [27. ... a5 - RMD] 28. cxb5 Bd6 [28. ... Rf8] 29. Rbd1 Re3+ [29. ... Rcd8] 30. Rd3 [30. Kc4] Rxd3+ 31. Kxd3 Kf7 [31. ... Ra8 to get some counterplay.] 32. h4 Kg6 [32. ... h5] 33. f5+ Kh5!? 34. Rh1 [34. f6] Bg3 [Despite Black's extra piece, the position is now actually dead even. With 34. ... Bc7 Black keeps some sort of edge.] 35. f6 gxf6 36. gxf6 Rf8 37. Rf1 [It's insanely difficult for the non-grandmasters among us to know if 37. Rf1 or 37. Rc1 is the correct move in this position. That is, which passed pawn should the rook get behind? Chessmaster suggests 37. Rc1, but since that passed pawn is supported and the King is closer to it, I like 37. Rf1 better myself. But what do I know?] Bxh4 38. c7 [38. Kd4! Kg6 39.

Review of "Chess Tactics for the Tournament Player"

If this book were truly representative of "the once-secret Russian method of chess training" no Soviet player would ever have become a grandmaster in the entire course of chess history. This book simply does not live up to the hype. Keep in mind as you read the following that according to the authors the alleged goal of these books is "to provide the knowledge necessary to reach expert strength." Nobody is going to achieve a rating anywhere remotely near expert strength using this book.

My complaints are numerous:
[1] These books violate the basic tenet to know your audience. The material oscillates between being absurdly simple for the alleged target audience to being absurdly unclear. For example, at one point they explain what a pin is. Elsewhere, they provide a complicated example from the Fischer-Spassky 1972 match with absolutely no commentary.
[2] The examples are too sparsely commented (an obscene number of them have no comments at all) to be of any use to a serious student trying to learn from them. As just one ridiculous example, page 180 contains a 19-move analysis with a single comment ("now follows a beautiful variation"); well, thanks, that was very useful. The famous game Lasker-Bauer, Amsterdam 1889, merits a comment on only one move as well.
[3] Many of the examples are downright useless, consisting as they do of a single move. That this book would have any one-move examples boggles my mind. We are given no indication of how the position was arrived at or how the magical move (1. Qa7!!) was decided upon or even why it merits two exclamation points.

On page 14, the authors write, "When studying lessons on tactics, pay close attention to both the means and circumstances that give rise to forced play." Yeah, that's what I thought I was reading this book for. Unfortunately, anyone looking to this book to learn this stuff will go away disappointed. Alburt & Palatnik clearly do not have the ability to teach tactics to their target audience. The book consists of vague generalities illustrated with examples of dubious instructional value.

The bottom line is -- if you are rated below 1600, you will not learn anything from Alburt & Palatnik; try Jeremy Silman's or Yasser Seirawan's books instead. If you are rated above 1600, you will not learn anything from these books either; try Dvoretsky's well-respected books (either the five books of the Dvoretsky-Yusupov school or Dvoretsky's more recent 4-volume School of Chess Excellence series).

Kasimdzhanov-Kasparov match is NOT a go

http://www.fide.com/news.asp?id=605
FIDE announces the termination of negotiations with the candidate organiser of the World Chess Championship match Kasimdzhanov-Kasparov, originally sheduled for January 2005 in Dubai. The organiser from Dubai did not supply FIDE with the required financial guarantees within the deadline set by the FIDE President.

The Kasimdzhanov-Kasparov match is now scheduled to be organised in spring 2005 and FIDE has already entered discussions with other candidate organisers and sponsors. Further information on the progress of these discussions will be officially announced until the end of this year.

Now let me see if I've got this straight. The January 2005 match in Dubai was just a figment of the FIDE President's imagination (as Kasparov suggested in his letter to the FIDE Congress), but this newly announced spring 2005 match with super-duper-secret unmentionable sponsors is legitimate. And we're supposed to believe this because...??? I can live with an idiot running things, and I can live with a crook running things . . . but a crooked idiot is too much to take. FIDE is turning professional chess into a bad joke. Can you imagine if Wimbledon or the Masters did not take place on schedule?
